python logging 重復打印問題

我的問題：

1. 在項目中由於在做個py文件中定義了handlers，導致在項目中定義幾次就會重復幾次

正確的處理辦法

1. 只在一個文件中定義內容，然后在其他的py文件中引用即可

import os
import logging
from logging.handlers import TimedRotatingFileHandler

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
# log file

LOG_FILE = os.path.join(BASE_DIR, 'data/info.log')

logger = logging.getLogger("Rotating Log")
logger.setLevel(logging.INFO)

handler = TimedRotatingFileHandler(LOG_FILE,
                                   when="D",
                                   interval=1,
                                   backupCount=5)
logger.addHandler(handler)
logging = logger

更新：

LOG_FILE = os.path.join(BASE_DIR, 'data/info.log')

logger = logging.getLogger("Rotating Log")
logger.setLevel(logging.INFO)
formatter = logging.Formatter('%(asctime)s - %(filename)s[line:%(lineno)d] - %(levelname)s: %(message)s')

handler = TimedRotatingFileHandler(LOG_FILE,
                                   when="S",
                                   interval=1,
                                   backupCount=5)
handler.setFormatter(formatter)
logger.addHandler(handler)


# file_handler = logging.FileHandler(LOG_FILE)
# file_handler.setLevel(level=logging.INFO)
# file_handler.setFormatter(formatter)

# 可以打印到控制台
# stream_handler = logging.StreamHandler()
# stream_handler.setLevel(logging.DEBUG)
# stream_handler.setFormatter(formatter)

# logger.addHandler(file_handler)
# logger.addHandler(stream_handler)

logging = logger
